地基

Archaeologists excavated for 5 months in the northern Greek region of Pella to uncover the base of the 58 square metre building, which was made from wooden poles, branches and mud.

考古学家在希腊北部佩拉地区挖了5个月，才发现这个建筑的58平方公尺地基；地基是由木杆、树枝及泥土制成。

Comparison with the other soil improvement methods, dynamic compaction has much technical superiority to deal with such non-uniform backfilled soils, but the correlative researches are relative fewer, therefore this is an important research subject.

强夯加固技术对此种回填土地基的处理具有诸多其他地基处理方法不可比拟的技术优势，但这方面的研究相对较少，因此这已经是实践对理论提出的一个重要研究课题。

Therefore it will be thought about whether the foundations intensify is overly evaluated through analyzing average concreting degree by slip circle method, it will be unsafe.

所以在圆弧滑动分析中计算的地基平均固结度来考虑地基强度的增长会过高估计填埋场的稳定性，是偏于不安全的。

It works by choosing appropriate gravel, scree, talus decries, coarse sand, medium sand, then ram them to be closely knitted. The sand gravel cushion can increase the bearing capacity of weak groundwork.

这种垫层法是用碎石、卵石、角砾、圆砾、砾砂、粗砂、中砂或石屑等坚硬、较粗粒径的回填材料，经合理级配并夯压密实后形成持力垫层，其主要目的是为了提高浅层软弱地基或不均匀地基的承载力。

From analyzing the change of effective stress in the process of one-direction to two-direction load, it is founded that the evanescing process of pore water pressure proposed in the paper shows a better agreement to fact.

从对单向荷载作用时地基的有效应力变化过程分析入手，引伸到对双向荷载作用时地基的有效应力变化过程分析，提出与实际情况更为符合的孔隙水压力消散过程。

combining with a actual example, interrelated technology of grouting on fragmentized goal groundwork had been researched and actualized.

摘 要：结合某工程实例，对老采空区破碎地基注浆的相关技术进行了研究和实施。确定了老采空区地基充填注浆的范围。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.

拱坝的地基一般是层状岩石地基，有的层厚度很小，这样就有多个岩层和坝体某层单元接触，本文根据岩基与坝体接触的几何关系，利用形函数的性质，提出24节点六面体层单元，这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的，其形函数采用可以拆分的形式表达，因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况，可以模拟一、二、三、四个棱边与错动带接触的情况，还可以退化为12节点的四边形面单元，以及五面体层单元。

So it is very important to theory and actuality by probing the regularity of soft soil, forecast the final consolidation by the forecast model and methodology from the actual settlement data.

因此深入探讨软土地基的沉降发展规律，利用有限的沉降实测数据，选取合理的预测模型及方法预测地基的后期沉降，对于控制施工进度，指导后期的施工组织与安排，具有重要的理论与工程实际意义。

Finally comes a conclusion of this essay that the load of the compounding subgrade increases in a certain degree, the settlement of soft and weak layer becomes relatively even and the maximum settlement correspondingly reduces by such flexible loads like road bank after setting gravel pile in the soft and weak subgrade.

本文最后给出了研究结论：在软弱地基中设置碎石桩后，在路堤等柔性荷载作用下，复合地基的承载力有一定程度的提高；软弱层的沉降比较均匀，最大沉降量相应减小。

Based on a brief introduction of the self-consistent method and the theory of soft foundation dealt with blasting method,this paper calculates some resilient modulus ,which are largely in accordance with the data in the experiments.

简要介绍了自洽方法和爆炸法处理软土地基的工作原理，并用自洽方法计算爆炸法处理的软土地基的回弹模量，计算结果和试验结果符合较好。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
